Joshua Jackson isn't ''freaked out'' by his girlfriend kissing another woman.

The 'Lay the Favorite' star's partner, Diane Kruger, locks lips Lea Seydoux in new film 'Farewell my Queen' - about a fictional love affair between French monarch Marie Antoinette and a servant - but the actor insists he isn't thinking about the scene.

When asked about the kiss, he told the New York Post newspaper: ''Any glib answer I give is going to come back to haunt me. It doesn't freak me out, really.''

However, he and Diane have recently returned from Paris Fashion Week and he jokingly claimed he was upset that none of the models kissed.

He quipped: ''Sadly, there were no women kissing.''

Joshua, 34, and Diane, 35, have been in a relationship since 2006 and he recently said they are ''working on'' starting a family.

He said: ''Kids are one of those things that kind of happen, aren't they?

''Certainly we're working on it if that's what you're asking.''

Both Joshua and Diane - who was previously married to Guillaume Canet for five years from 2001 - have previously insisted they have no desire to tie the knot, and though it is still not ''important'' for them to make their union official, they won't rule it out completely.

Joshua said: ''It's important for the people that it's important for, but neither One Of Us are particularly religious so I don't think that there's any particular push. But never say never.''
